![]() ![]() Accepts standard PF30 cups for but the wider shell requires a BBright-compatible crankset adaptors are available that permit the use of 24mm spindle cranksets (i.e.Wheels Manufacturing Eccentric BB For BB30 & 24/22mm (SRAM, Truvativ) Cranks. BBright Press Fit is a variant of PF30 with an asymmetric wider shell (11mm offset to the non-drive side) bearings are contained inside cups and the cups are pressed into the frame Wheels Manufacturing BB86/92 Thread Together ABEC-3 Bottom Bracket.Accepts standard BB30 bearings but the wider shell requires a BBright-compatible crankset.Most modern cranksets have the BB spindle integrated into the driveside crankarm. Older model road and mountain bikes have square taper spindles, but the more common standard among performance bikes today is a splined interface with the crank. BBright Direct Fit is a variant of BB30 with an asymmetric wider shell (11mm offset to the non-drive side) bearings press directly into the frame and stop at removable snap rings. This design allows for wider spindles and increased stiffness.Shell width will measure 79mm (road standard only).It seems that this is what your are looking for. 'We currently make bottom brackets and adaptors for BSA, BB30, and PF30 frames and are working on BB86 bottom brackets. Currently used exclusively on Cervelo bicycles An excerpt from it: 'The BB386 EVO cranks are compatible with almost every BB shell standard (BSA, BB30, PF30, BB86),' says Jason Miles of FSA.Bearings press directly into the frame and stop at an integrated raised step inside the shell bore snap rings are not used.Shell width will measure 90.5mm (road) or 95.5mm (mountain).Currently used exclusively on Trek bicycles.Designed specifically for 24mm spindle cranksets originally intended for external threaded cups (i.e.Bearings are contained inside cups which are pressed into the frame shell has a stepped design but there are no snap ring grooves.Shell width will measure 86.5mm (road) or 91.5mm (mountain).The shell will have a smooth bore (no snap ring grooves) the outer lip of the cup contacting the frame is what stops the press action.Both PressFit 30 and BB30 use the same 30mm ID bearings and 30mm spindle cranksets the difference is that PF30 bearings are contained inside cups and the cups are pressed into the frame.Designed for BB30 30mm spindle cranksets adaptors are available that permit the use of 24mm spindle cranksets (i.e.Bearings press directly into the frame and stop at removable snap rings two snap ring grooves will be present inside the shell.Shell inner diameter (ID) will measure 42mm BB30 bearings have a corresponding outer diameter (OD) of 42mm.Shell width will measure 68mm (road) or 73mm (mountain).The table at the bottom of the page is useful for quick comparisons. This document details the critical factors that differentiate one press-fit standard from another. Press-fit bottom bracket shells are not threaded instead the bearings or cups are pressed into the frame. ![]()
